through the rubbing Of smachine cry with q
rag saturated with the fluid. This would
show that there is need of caution in the
handling of this commonly used liquid.
q, IRREGULARITY Of the pulse is not an alarm
ing symptom, as many suppose. Ina lecture
tothe Royal College Of Physicians, London,
it was stated that it may occur in perfect
health up to- extreme old age, Another
common error is that the tension Of q mans
pulse may indicate the vigor Of his body or
mind. st5 Z
In regard to the value Of skim milk as
food, it is said: In gallon Of skim milk
there is nearly a pound Of solid food, almost
chemically similar to the lean Of meat.
This is the flesh of the milk, and there is no
reason why it should not be eaten as food,
just as meat is eaten, with the addition of
any kind Of pure foreign fat; but being
mixed with a liquid, the people are unable
to appreciate it, and rarely perceive the
fact that it is food at all. rs r. e. sss,.,
AN eminent astronomer asserts that the
alleged periodical changes Of the diameter
Of the sun do not exist. His researches,
which are founded on nineteen series of OBJ
servations twelve of which refer to the
horizontal diameter, and comprise q, 900 OBJ
servations, while seven refer to the vertical
diameter-show that the periodical changes
are due to the influence Of the temperature
upon the instruments with which the OBJ
servations were made, and that for this
reason the period corresponds to that of the
annual period of temperature. igY
IT has been found that the intemperance
of parents is q considerable factor in pro-
ducing idiocy in children. This has been
confirmed by French physicians, one of
whom has said that in the village Of Car
eme, whose riches were in its vineyards,
ten years comparative sobriety, enforced
by vine-disease, had sensible effect in
diminishing the cases of idiocy. Nervous
constitution and consumption exercise i'm
portant influence. OF the professions, law
yers furnish the smallest proportion of
idiots, while they are credited with the pro-
creation of a relatively very large number
of men of eminence.
THE process of welding by electricity is
now being industrially applied; it being
largely employed in the manufacture of
metallic tanks and reservoirs. The pieces
to be welded are placed upon cast iron
plate supported by an insulated table and
connected with the negative pole of source
of electricity. The positive pole communi-
Gates with an electric carbon inserted in an
insulating handle. On drawing the point of
the carbon along the edges of the metal to
be welded, the operator closes the circuit.
He has then merely to raise the point
slightly to produce voltaic arc whose high
temperature melts the two pieces of metal
and causes them to unite. The intensity of
the current naturally varies with the work
to be done.
